Hi,
I am able to import .XLS file in my C# project but when i try to import .XLSX file (into DataTable) i am getting following reference issues.

1. Could not load file or assembly 'ICSharpCode.SharpZipLib - (I had found and added in my project)
2. Could not load file or assembly 'NPOI.OpenXmlFormats, Version=2.2.0.0 - (I could not found the .dll file, please provide me this file)

Please also let me know if the above can resolve my issue.

When i run the test [TestParseTextFromWord] in [Word2003ParserTest] i get the flowing exception

System.IO.FileLoadException : Could not load file or assembly 'NPOI, Version=2.1.3.1, Culture=neutral, PublicKeyToken=0df73ec7942b34e1' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
at Toxy.Parsers.Word2003TextParser.Parse()
at Toxy.Test.Word2003ParserTest.TestParseTextFromWord() in Word2003ParserTest.cs: line 18
and the NPOI referenced in the Toxy Project is NPOI Version=2.2.0.0 and it says it's need Version =2.1.3.1 what is the problem?

最近业余时间把一个庞大的应用框架迁移到 .NET Core 2.1 上了，改动比想象中小很多，除了 Mvc 部分微软重写了改起来比较多以外，其它倒还挺顺利的，启动速度缩减到了原来的一半。

Toxy 有计划支持 .NET Core 吗 ？

It would be nice to be able to import fixed panes or that they are unfixed.
People always forget unfixing before saving.

Have a sunny weekend ...

I have an Excel file which contains 5 spread sheets out of which:
• 2 are hidden (as they are dialog, user interface, kind of sheets DlgView1, DlgView2).
• 3 work sheets (WrkSht1, WrkSht2, WrkSht3) are visible with some data containing formulas and external links.
Also, the Excel sheet contains a VBA module called Module1.bas with some logic. When I check the number of worksheets using workbook.NumberOfSheets property, it shows 5, but when I iterate through the code for all worksheets present, I get the below results:

1. Sheet1 = DlgView1 -------> which is hidden
2. Sheet2 = DlgView2 -------> which is hidden
3. Sheet3 = Module1 -------> which is hidden --->This is what is confusing!!!!
4. Sheet4 = WrkSht1 -------> which is visible
5. Sheet5 = WrkSht2 -------> which is visible
   It should have been like this instead I suppose:
6. Sheet1 = DlgView1 -------> which is hidden
7. Sheet2 = DlgView2 -------> which is hidden
8. Sheet3 = WrkSht1 -------> which is visible
9. Sheet4 = WrkSht2 -------> which is visible
10. Sheet5 = WrkSht3 -------> which is visible
    I cannot get access to one of the visible worksheet WrkSht3 as the count(= 5) of worksheet ends by this time.
    Also, when my code sets to play around different cells of worksheet WrkSht1, it will actually be pointing to WrkSht2 and for worksheet WrkSht2, it will actually be pointing to WrkSht3. But WrkSht3 was never initialzed as a worksheet as seen from the above results.
    For testing purpose, I deleted Module1 and checked, it works fine with count as 5 and considering all the worksheets (DlgView1, DlgView2, WrkSht1, WrkSht2, WrkSht3) to process.
    Also, to mention, I get an exception thrown while working with this file & not with any others:
    "Unsupported BOF found of type VBModule"
    My question is:
    Does NPOI or POI treat a VBA module in a Excel sheet as a hidden worksheet?
    • If not, why is the code considering Module1 as worksheet and not the actual visible worksheet WrkSht3 as explained above.
    • If yes, is there a way to tell code not consider VBA Modules as worksheets and also actual visible worksheets like WrkSht3.
    If needed, I can send the Excel sheet which I am working on. Thanks

Hello,
I am working on a NPOI project & I need to know how to access the external links with respect to .xls & .xlsx files. I am able to work with rest all kind of objects but not with External links. When I access the cell formula, in .xls files, I get only the external file name but not the path it is pointing to whereas in .xlsx file, I dont get external file name but numeric value like [1] or [2] ect. Can anyone just let know how to access at external links using NPOI for .xls and .xlsx files. I looked at apache POI counterpart and they have method called getExternalLinks() through which we can get at external links but not in NPOI. Thank you.

你给我举几个例子npp怎么**了？我也爱国，但我没觉得他**啊。

知乎虽然是**网络的**明灯了，但关键字过滤还是绕不过，被政府约谈过很多次了，我也不怪他，所以还是来这里聊吧。

Just tested with a docx document and it doesn't extract any text from the header. Is it possible to fix?

It was removed and I cannot find how to parse RTF files. Is it possible?

How to Extract EPUB Files? An .epub is a popular extension that is used for electronic publications.

I am trying to find a way to extract text from a instance of System.IO.Stream(not only FileStream),but Toxy can only do extraction work when source is a file,actually,the source may varies for some reasons.Can you add the stream support to ParseContext,tell me if you have any tech problems,we could work it out together.

@tonyqus 可以给一个解决方案吗？Toxy如果不能在.net core上使用，就要移花接木用Java的 tika了

I cannot parse any newer PDF files because PDFSharp throws an error due to a bug where it cannot read >v1.5 of PDFs. Is there anything we can do to fix this?

PDF document parser can't properly handle paragraph and page counts. Paragraphs array shows lines instead of paragraphs and total page count is zero.
